IP Spam Blacklist & Spam Database (DNSBL) Guide
An IP Blacklist (DNSBL) is a security blocklist database that gathers and shares IP addresses with records of malicious behaviors, such as mass spam mailing, malware distribution, or hacking attempts.
Key Features
- Global Blacklist Audit: Checks against key databases trusted by international mail servers and firewalls (Spamhaus, Barracuda, etc.).
- Real-time Parallel Scanning: Queries multiple blacklist servers concurrently, delivering fast results without delay.
- Security Assessment Level: Rates your IP address into 3 security tiers (Clean, Warning, Danger) based on block counts.
How to Use
- Why is my IP registered on a blacklist?: Even if you did not perform malicious activities, you could be listed if you share a dynamic IP pool with an offender, or if your device was infected with malware that sent out spam without your knowledge.
- What happens if my IP is blacklisted?: You might experience issues such as being blocked from sending emails (receiving bounce-backs or spam-bin sorting) or being prompted with excessive Captcha verification on popular websites.
- How can I delist my IP from blacklists?: You can search your IP on the blocklist provider's official website and submit a delisting request (usually processed for free within 1–2 days).
